2.6.9 exchange rate structure change and reports

[Wm...]

I'm not sure if I'm missing something but should reports, e.g. balance 
sheets, know about the fact that exchange rates that were

   fraction buys 1

are now

   1 buys many?

My reports seem to be stuck at the exchange rate last collected using 
the 2.6.8 structure.

Hopefully I'm doing something wrong otherwise all reports involving 
currencies that inverted are going to be increasingly out of date over 
time.

An example of not-insignificant currencies inverting is GBP / USD
